Besides, we already invaded Canada on Southpark, and it just didn't work out...
this crap keeps up, they'll be the ones invading us.  we'll have to align with the Quebecois.
Yup, we'll be marching down soon... LOL

No, no invasion of Canada needed, the US is already our number one - really the only - export market for Canadian energy.

Plus we have all the uranium up here, watch out.

More seriously, Canada is the largest customer of some 30 or 31 of all the states - screw around with relations too much and the resulting trade war will hurt both sides.

Of course, a conspiracy theory could be built that fomenting some sort of revisit to the depression of the 1930's would be the best solution for an energy starved world.

Then again, that sort of decision would only be contemplated by people who recognize that there's a permanent crisis looming, and somehow I don't think we are there yet.

(in terms of recognition of the potential)
